Application filed June 6, 1918. Serial in. 238,421.

To all whom it may concern:

Be it known that I, EDWARD T. CURRAN, a citizen of the United States, residin at Detroit, county of Wayne, State of Michihave invented a certain new and useful rovement in Radiators, and declare the fol owing to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to radiators for use in connection with steam or hot water heatin installations and relates particularly to ra 'ators for this purpose in which the radiator sections are made up of stampings from sheet metal welded together to form a tubular structure, and the sections mounted in juxtaposed relation upon a tube or'tubes passing through openings at one or both ends of the sections, and .connected in circulation by perforations in the tube or tubes communicating with the respective sections and whereby the radiator is connected in circulation with a steam or hot water so ply. 7

t is theobject of the invention to improve the general construction of radiators the flow of the heating medium will be acilitated and the forming of pockets obviated, facilitating the complete emptying of the radiatorsectlons of watersof condensation when utilized as a 1 steam radiator, or the complete emptying of thewater therefrom when used in connection with a hot water heatin installation and thereby increasing the e ciency of the ra- Ll: anywaters of condensation therefrom which ma ,;;l;ave collected in the radiator sections amlicause the flow of steam through and the heating of. all of the radiator sections simnltaneously, and when used inconnection 50. within hot water heating installation to cause simultaneously the flow of the heated water-to and eduction of the cold water frontal] of,,the sections, instead of successively through the sections.

Specification of Letters Patent.

Other objects and advantages will hereinafter appear. In the drawing accompanying and formmg a (part of this specification Figure, 1 is an en elevation of a radiator constialcted in accordance with my invention.

Fig. 2 is a sectional side elevation of a radiator showing the embodiment of my invention.

Fi .-3 is an elevational view looking at v the side of a radiator section.

Fig. 4 is an enlar ed sectional view, of

shown in Fig. 2 to illustrate the relation of Y the pipe for the ingress of the heating medium and the connection thereof to the radiator sections; and

Fig. 6 is a sectional view of one of the radiator sections taken substantially on the line m-m of Fi' 1 to show the cross sectional shape of t e radiator sections.

Similar characters of reference designate like parts throughout the different views of the drawing.

In carrying out the invention the radiator is built up of a number 'of tubular sections assembled in juxtaposed relation in accordance with the desired size of radiator similar to the prevailing practice, and shown in the drawin as consistingof six sections or units. Eac of the radiator sections is made up of a pair of similarly shaped members A and B stamped from sheet metal of any do? I sired cross sectional shape and in the present instance of the cross sectional shape shown in Fi 6, whereby as the two sections are to ether they will contact. adjacent! plac the latera edges and at which point they are welded together, and intermediate portions extending. longitudinally of the members contacting, as shown at D, D, and at; which point the sectionsare secured together as by riveting or spot welding, the longitudinal portions not only serving as strengthening ribs but forming a three columnyraa-adiator section, or three passa vforI the flow-of the heating medium. members A, B of the, radiator sectionsare provided with perforations or openings E,

ach of the J preferabl circglar inform, atopposite ends and so a a y 'when the members are brou ht and wel ed together these openings will he in axial alinement with a portion of the circumferential wall of the openings tangent to the inner surface at thelowest and highest pointv in a radiator section, as cleard'y shown in F i 1 and 4 for a purpose to be h ftei- .r V

A pipe F for the inlet of the. heating medium passes through the Tower openings of pections and upon which pipe the radiator sections are mounte in predetermined spacedrelation and fixed thereto in steam or. water tight, connection as by welding. F is of such length as to accommoda te the number of sections which are-to conriv pipe The lower portion of the wall of the stitute the radiator. One end ofthe pipe is threaded for connection to a source of supply of'the heating medium and the opposite end is closed by suitable means, or the per- Amuse at the lower end of the outermost memberof v e last section of the radiator, whichjs at t left as shown for instance in Figs. Qiand ,4, being unperforated at the lowerend and, which the end of the F may abut and close said end of the r v and 5 is comparatively small, as shown at g,

. Home and the openings sively-increasing'in size any, with the langest opening at the extremity of the pipe orzopening into the lastisection at the extreme left as viewed from 2 and 5-. By this arrangemeht the in'c heatin medium, or the greater portionthereof, ta the course of the la 'at the'extremit of the pipe 1!! I m with t section at theleit, and as the pressure of the heating mefimgr phasing out thmugh the perforatidnsm' 'opdnings of the pipe in communication with the othersections will be :less than sihe'iqmessiire of the heating dis- I froin said la'r'ge opening any waters en'satio'n in the lower portion of the ra r"wfll:be caused to flow or be drained fmm'the iiadiator, this is particularly single pipesystem is need as in a of-steam heating installation. Fa H. 'by'thisarrangemnt of havin thebutlet or the heating medium at the lowermost @part'ofa radiatoror radiator secthrou h and le ser theseetions of the :iail .1 Li} I I 'p 'F r the egress of the heati medium, as in a ct water heatin' installation, a ip F engages in openings at the ends of t e radiator sections opposite to the pipe F, and shown iii'the drawing at the -top,secured to the sections in water or steam ti ht connection the same as the pipe F. 'l his pipe is also provided with cut outs or perforations to connect the same in circulation with the radiator sections, the egress or outlet end of Fig. 2. The openings in'this pipe am also ofeprogressingsize but the openi of smallest size is adjacent thegoutlet en of the pipe, as shown at g, and progressively increasing in size to the opposite end, as shown at g. The end of thepipe opposite to the threaded end is closed by abutting against the unperforated outer member of the radiator section at the extreme right as viewed from Fig. 2. By this arrangement the heating medium entering the pipe Fithe greater portion of which will tend to How through the largest opening at the, extremity of the pipe taking the courseofleast resistance will pm up throughtheend section at the left, and as the outlet from this section or connection thereof with the pipe F is restricted it will tend to force any air out of said section in a steam heating installation and retard theflow of and place the steam therein in compression the excesspressure facilitating the discha of waters of condensation from the pipe as hereinbefore set forth and causing the steamwith greater force or pressure to be 'discharged through the'other connections between the radiator mnections "and pipe. By the arrangement of the perforations in the pipes F and F the pressure of the heating medium in the radiator sections is halancedr By the arrangement of the hunger perforation in the pipe F opposite to the small perforation in the ipe F and then progressively decreasing t e perforationsih the pipe F from "the larger shown, and increasing the size cessive openings in the p e F from the r e, B

smallest at the discharge of F,

of the mica substantially even and uniform i'essifieis maintained mall times in the ra iator 'sections.

A radiator constructed as r may be supported in any eenveatiehal manner, and is as liy "legs -H, the

legs being arranged or or seen size relative to each other that the one end 'of'the iafiator I will be slightly higher than v fitlili' end thereby a the saaiami' maintains the were of the from the Eadie?!- waters of I i "when utilized in a steam heating installation,

and the draining of all the water from a radiator in a hot water installation.

What I claim is:

1. In a radiator of the class specified, a series of hollow sections, and an mlet pipe for the heating medium passing through the lower portion of the successive sections, said pipe having outlets opening into each of the radiator sections tangent wlth the inner surface of the lowermost part of the radiator sections and said openings for successive sections increasing progressively in size in the direction of travel of the heating medium for the purpose specified.

3. In a radiator of the class specified, a series of hollow sections, an inlet pipe for the heating medium passing through one end of the sections and having openings one leading into each of the sections and progressively increasing in size in the successive sections in the direction of flow of the heating medium, and an outlet pi e passing through the opposite ends of t e sections having openingsone in communication with each of the sections and progressively decreasing in size in the successive sections in the direction of flow of the heating medium for the purpose specified.

4. In a radiator of the class specified, a series of sections each section having an inlet in communication with the source of the heatin medium, and an outlet pipe assing throu one end of said sections aving openings one in communication with each of the sections, said openings progressively decreasin in size in the successive sections to the out et end of the pipe and being tangent with the inner surface of the uppermost part of the radiator sections for the purpose specified.

5. In a radiator of the class specified, a series of hollow sections consisting of similarly formed sections welded together at the edges; an inlet pi for the heating medium passing throug one end of the sections having openings leading into the lowermost portion of and progressively increasing in size in the successive sections; and an outlet pipe passing through the opposite ends of the sections one in commumcation with each of the sections and leading from the uppermost portion of the sections, said openings progressively decreasing in size in the successive sections in a direction with the progressive increase in the'size of the openings of the inlet pipe for the purpose specified.
